Abstract

A permanent magnet machine (10), a rotor assembly (12) for the machine, and a pump assembly (100). The permanent magnet machine (10) includes a stator assembly (14) including a stator core (56) configured to generate a magnetic field and extending along a longitudinal axis with an inner surface defining a cavity (36) and the rotor assembly (12) including a rotor core (30) and a rotor shaft (22). The rotor core is disposed inside the cavity and configured to rotate about the longitudinal axis. The rotor assembly further including a plurality of permanent magnets (34) for generating a magnetic field which interacts with the stator magnetic field to produce torque. The permanent magnets configured as one of internal or surface mounted The rotor assembly also including a plurality of retaining clips (40) configured to retain the plurality of permanent magnets relative to the rotor core. The pump assembly including an electric submersible pump (104) and a permanent magnet motor for driving the pump.
